Hello!

When solving a quadratic equation, we should begin by confirming that the right side is equal to 0. The equation above, however, contains a 2 on the right side.

Therefore, the most logical first step would be to subtract 2 from both sides, leaving the ride side equal to 0.

I hope this helps!

Answer:

Option D is correct.

Step-by-step explanation:

x^2-4x+16= 2

In order to simplify the equation the first step is to subtract 2 from both sides to make 0 in the right side and converting it in standard form

ax^2+bx+c=0

therefore   option D is correct

The graph of a function f is shown. Use the graph to estimate the average rate of change from x = –2 to x = 0
vodomira [7]

Answer:

Average rate of change = 2

Step-by-step explanation:

Formula to get the rate of change of a function between x = b and x = a is,

Rate of change = \frac{f(b)-f(a)}{b-a}

We have to calculate the average rate of change between x = -2 and x = 0

From the graph attached,

At x = -2,

f(-2) = 0

At x = 0,

f(0) = 4

Therefore, average rate of change = \frac{f(0)-f(-2)}{0-(-2)}

                                                          = \frac{4-0}{2}

                                                          = 2

Average rate of change of the given function between x = -2 and x = 0 is 2.
